Description Scleral contact lenses create an elevated chamber over the cornea that can be filled with artificial . The base or haptic is fit over the less sensitive sclera. Scleral contact lens has been proposed to provide optical correction, mechanical protection, relief of symptoms, and facilitation of healing for a variety of corneal conditions. Specifically, the scleral contact lens may neutralize corneal surface irregularities and, by covering the corneal surface in a reservoir of oxygenated artificial tears, function as a liquid bandage for corneal surface disease. This may be called prosthetic replacement of the ocular surface ecosystem (PROSE). The development of materials with high gas permeability and technologic innovations in design and manufacturing has stimulated the use of scleral lenses. The Boston Ocular Surface Prosthesis (Boston Foundation for Sight) is a scleral contact lens that is custom fit using computer-aided design and manufacturing (i.e., computerized lathe). Another design is the Jupiter mini-scleral gas permeable contact lens (Medlens Innovations and Essilor Contact Lens). The Jupiter scleral lens is fit using a diagnostic lens series. The Procornea (Eerbeek) scleral lens was developed in Europe. There are 4 variations of the Procornea: spherical, front-surface toric, back-surface toric, and bitoric. Lenses are cut with submicron lathing from a blank. All gas permeable scleral lens are considered investigational regardless of the commercial name, the manufacturer or FDA approval status except when used for the medically necessary indications that are consistent with the policy statement.

5 Summary The literature on gas permeable scleral contact lenses consists of a number of large case series that enrolled more than 100 patients. The largest series was a retrospective review of more than 538 patients with more than 40 different clinical indications who were fitted with the Boston Ocular Surface Prosthesis. These case series report an improvement in health outcomes in patients who have failed all other available treatments. These uncontrolled studies are suggestive of benefit, but the lack of controlled trials precludes a definite conclusion on treatment benefit. Clinical input was obtained and supports the medical necessity of the gas permeable scleral contact lens in cases of corneal ectatic disorders, corneal scarring and/or vasularization, irregular corneal astigmatism, and ocular surface disease with pain and/or decreased visual acuity when all other available treatments have failed. For patients with ocular surface diseases who have not responded adequately to topical medications, there is a lack of alternative treatments. For patients with corneal ectatic disorders and irregular astigmatism who have failed standard contact lens, the alternative of corneal transplant surgery is associated with risks. Therefore, the gas permeable scleral contact lens may be considered medically necessary in these patient populations.
